Comment:

 Hi Colin,

 Our monitoring system checked the fallbacks this morning, and found that
 25% of them are down. So we should generate a new list of fallbacks in the
 next few weeks.

 Here's what needs to be done:
 * you can do a final call for opt-ins, if you'd like (#24803)
 * Do a final update to the whitelist (#24805)
 * I'll make the fallback script ignore addresses in the whitelist (#24838)
 * I can merge the changes from #24805, #24838, and #26502 into a branch
 (or master)
 * We can both run the fallback script from that branch to generate a
 fallback_dirs.inc file (#24803)
   * Last time, pastly and I ran the script, and then we merged our results
 together
 * I can write a changes file (#24803)
 * I can backport the list to src/or/fallback_dirs.inc in maint-0.2.9
 (#24803)

 The changes file looks like:
 {{{
   o Minor features (fallback directory list):
     - Replace the 177 fallbacks originally introduced in Tor 0.2.9.8 in
       December 2016 (of which ~126 were still functional), with a list of
       151 fallbacks (32 new, 119 existing, 58 removed) generated in
       May 2017.
       Resolves ticket 21564.
 }}}
 But I think I might need to tweak the wording to pass make check-changes.
